After teaching his class all about roman numerals (X = 10, IX=9 and so on) the teacher asked his class to draw a single continuous line and turn IX into 6. The only stipulation the teacher made was that the pen could not be lifted from the paper until the line was complete.

by any chance was there folding of the paper?

Mark

write the letter S in front of IX to form SIX

doh!

A man was born in 1955. He is still alive today aged 33 - how come?

he's been in a time machine of course...

Ned.

give up, assuming the time machine idea is wrong?

Mark

Is it still 1988? Hooray!!!!

got you - no time machine involved...

not cryogenically frozen then either?

maybe he's been travelling near the speed of light, hence time has passed but passed slower for him. there is an astronaut who is 1 second in the future as he's been in space travelling in orbit at a zillion miles an hour for ages...

Ned.

...maybe not...

Think of it laterally...

I am.... the annoying thing is I'm sure I worked this out before, and I think thats why I cant work it out now

Mark

it really is very simple - think of what the question actually TELLS you - you're making it far more complicated than it is...

This is to be solved in the head, without paper and pencil.

1, it is regular coffee.

It could have been the zip code, telephone code, street number, house number, etc etc

A plane flies from Athens to Brussels at maximum speed. Nor­mally, flying at maximum speed would enable it to reach Brussels in four-fifths of the time that it takes to fly there at cruising speed. On this occasion, however, the velocity of a favorable wind enables it to get there in only half the time it would normally take at maximum speed. On the return journey, it leaves Brussels at 1 p.m. Ignoring time zones, and encountering the same velocity and direction of wind, at what time will the plane arrive back at Athens?

---

Its runs out of fuel before it gets there

unless I'm mistaken you need 1 more piece of information?

Mark

the head wind must be the same as the planes maximum speed, so it couldnt actually fly up wind at all. so as said, it would run out of fuel for sure!

Hellfire,

I haven't bothered serarching, but what website are you getting these logic brain teasers from?

Ned.

Ned - if I told you that I'd have to kill you
